Headlamp Aiming

The vehicle has a visual optical headlamp aiming

system. The aim of the headlamps have been

preset at the factory and should need no further

adjustment.

However, if the vehicle is damaged in an accident,

the aim of the headlamps may be affected and

adjustment may be necessary.

If oncoming vehicles ﬂash their high beams at

you, this may mean the vertical aim of your

headlamps needs to be adjusted.

It is recommended that the vehicle is taken to your

dealer for service if the headlamps need to be

adjusted. It is possible however, to re-aim

the headlamps as described in the following

procedure.

The vehicle should be properly prepared as

follows:

• The vehicle should be placed so the

headlamps are 25 ft. (7.6 m) from a light

colored wall.

• The vehicle must have all four tires on a level

surface which is level all the way to the wall.

• The vehicle should be placed so it is

perpendicular to the wall.

• The vehicle should not have any snow, ice, or

mud on it.

• The vehicle should be fully assembled and all

other work stopped while headlamp aiming is

being performed.

• The vehicle should be normally loaded with

a full tank of fuel and one person or

160 lbs (75 kg) sitting on the driver’s seat.

• Tires should be properly inﬂated.

• The spare tire is in its proper location in the

vehicle.

Headlamp aiming is done with the vehicle’s

low-beam headlamps. The high-beam headlamps

will be correctly aimed if the low-beam headlamps

are aimed properly.
